Trophy Guide / "Unlocked" achievement

This is the result of the game that will take you more time, and also the one that basically explains how to "dilate" the playing time of an otherwise very short title.

The trials of MGS Ground Zeroes work like this: Play a mission and complete it by unlocking the trial for that mission. Then you'll have to replay and complete the mission again by completing the newly unlocked trial, which will unlock another trial ... and so on.

There are different tests for each mission, both on Normal difficulty and Hard difficulty, and to complete everything you will need to unlock them all.

Below is a list with all the tests to unlock. In the game menu you can check your progress, the blocked trials are indicated with "???", for these you will not be able to see the name. You will unlock the "Unlocked" trophy when there are no more question marks in the list.
